How is your power bill?

Recently I moved my equipment to our vacation home south of the border. On average the power bill ran about $12 per month. After setting up the three Krell Amps (fpb 350s and a KSA 150) to drive the Maggie 20.1s, etc. and, in addition to listening to music, starting watching nightly action movies through the system as well. The new power bill was almost $70.00!!

Thoughts? Your experience with this?
